Page 1 of 5

There may be some debate as to whether activist shareholders are good for the long-term health of companies, but there is no debating their results. In 2012, 2013, and 2014, activist investment strategies returned 9.3%, 19.2%, and 8.5% respectively per year. While new activist positions may not be moving the needle quite as much as they once were, the market still values activist involvement in companies. In this article, we reveal one of the latest activist filings, issued by Caledonia Investments PLC, disclosing the latest information regarding the activist’s position in Bristow Group Inc (NYSE:BRS). The filing discloses a position of 2.82 million shares and declares that Caledonia Investments purchased about 600,000 shares over the past few days believing them to be undervalued after a brutal stretch for the stock, which is down by 43% year-to-date and 76% over the past year. The filing is embedded in its entirety below and on the following pages.
